Paypal will debit 1$ or 2$ to verify your bank card. Check your Account balance if you have online banking or wait for the statment to arrive. look for the transaction from Paypal and look for the 4 digit. I don't remember the exact digit but paypal should have informed you on the digit.

Use this 4 digit from your bank statment in your paypal account. Login to your paypal and then type the 4 digit to activate your paypal account

Your Money will be refunded to your account which is either 1$ or 2$ after the activation is completed.
